Apple Logic Pro /LogicExpress Discussion

Hey

I'm very new to Logic (and music technology in general!!) but am loving it.  I'm using Logic to 
create backing tracks for singers and theatre using software instruments - and I need some 
very basic help...

I've bought and downloaded various drum samples - all different kinds.  Now - how do I do 
create drum patterns.  I'm not sure of the terminology....so I'm not gonna embarass myself!  
Can someone give me some tips, step by step!  And recommend some products to buy or 
download.


Also - in a similar vein - those bits of software that you apply to guitar sounds to do rhythm 
patterns.


Many thanks in advance for your help!!!
